Q at night solar inverter

Are SMA inverters compatible with Q at night?

SMA inverters can provide reactive power during the night and meet the reactive power needs of additional generators and on-site or utility grid loads (taking into consideration their power limit). With the increasing number of PV power plants connected to the utility grid, the need to provide reactive power at various grid feed-in points is also on the rise.

Can SMA inverters provide reactive power at night?

SMA inverters can provide reactive power during the night (displacement power factor setting ≠ 1). With Q at Night, PV power plants that implement plant solutions from SMA can now meet the demand for reactive power at night.

Is Q at night viable?

The reactive power can be as high as 60% of rated active power at night. Special rectifier hardware is added to the inverter, and the inverter must be kept connected to the grid at night. There must be incentives for developers and owners for Q at Night to be viable.

What does Q represent?

In this context, Q represents the capability of PV power plants to provide reactive power at night with SMA's plant solutions.

Why do PV power plants need inverters?

Inverters are essential for PV power plants because they generate the reactive power required for operability of technical equipment. This reactive power can be fed decentrally into the utility grid at the grid-connection point and can even be supplied during the night.

Can a PV plant feed in reactive power during the night?

In addition, it is also possible to compensate the needs of additional generators through the extra reactive power available, offering an additional source of income. In order for the PV plant to also feed in reactive power during the night, the inverter must be fitted with the “Q at Night” option.
